New Section: 210.19(A)(5) Voltage Drop. Conductors for branch circuits as defined in Article 100 shall be sized to prevent a voltage drop not exceeding 5% at the farthest outlet from the point the branch circuit receives its source.
Substantiation: The CMP needs to stop considering this issue a design factor and a matter of efficency. The scope of the code is for the protection of persons and property. Excessive voltage drop on a circuit results in excessive heat and causes damage to equipment with specified voltage ratings. Limiting voltage to 5% helps to ensure conductor insulation integrity, proper operation of equipment and appliances, and proper operation of overcurrent devices.
